ok, I tried to fit the rc 310cc injectors into my 94 b18b stock manifold and they will just not go. I had these same exact ones in my 99 ls (part # sl2-310) and they were snug, but fit perfectly. However I noticed that the injector hole in my 94 looks like it is stepped down (smaller) then the injector itself. The hole is definitley not big enough. Does the intake manifold have to be drilled out a little larger or something???I am sick of fooling with these damn injectors.... Can anyone shed some light on this please.....

 

Anyone??????
